Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
If you have about five minutes and you can't get enough information about the new 'Vette, then check out the videos posted below.

2014 Chevy Silverado priced from *$24,585, V8 gets better economy than Ford EcoBoost V6

Chevrolet has thrown down the next hand in the pickup truck poker wars and revealed at least a couple of potential aces - depending on which numbers matter most to you. The 2014 2014 Silverado 1500 with its 5.3-liter EcoTec3 V8 gets 335 horsepower and 383 pound-feet of torque, is mated to a six-speed automatic, can tow 11,500 pounds with the optional Max Trailer Package and costs the same as the outgoing Silverado, $24,585 (*including $995 destination fee). Chevy says the Silverado also stands atop the fuel economy charts when comparing any competitor with a V8 engine - and some competitors with V6 engines. The two-wheel drive model returns 16 miles per gallon city, 23 mpg highway, 19 mpg combined in two-wheel drive guise and 16 mpg city, 22 mpg highway and 18 mpg combined as a four-wheel drive.
For context around those numbers, the most fuel efficient V8-powered 2013 Ford F-150 pickups lose about two mpg in every metric compared to the Silverado, the 3.5-liter V6 EcoBoost returning 16 city, 18 highway and 22 combined in two-wheel drive. However, that EcoBoost does have 365 hp and 420 lb-ft of torque. You can get a Ram 1500 with a 3.6-liter V6 that gets 25 mpg highway, but it has 305 hp and 269 lb-ft of torque. The 2013 Ram with the 5.7-liter Hemi V8 and its 395 hp and 407 lb-ft drops one mpg in every category to the Silverado. Its tow rating is 200 pounds beyond its nearest competitor, the F-150 with the Max Trailer Tow Package.
Elsewhere, the new Silverado gets a quieter cab with a redesigned interior, a new bed with improved load-management possibilities, disc brakes all around, tweaked steering and suspension, along with free standard scheduled maintenance for two years or 24,000 miles.
